NON-LINEAR VIDEO EDITING ENGINE • ASWF OPENTIMELINEIO & CMX 3600 EDL

Pure Rust Multi-Track NLE, Cubic Bezier Keyframes & Universal Timeline Interchange.

kubeezcut-rs compiles non-destructive multi-track editing (split, trim, slip, ripple delete), 16-step bisection Cubic Bezier & harmonic spring keyframe animation, WebGPU shader color pipelines, and zero-overhead export to Academy Software Foundation OpenTimelineIO (.otio), SMPTE CMX 3600 EDL, Final Cut Pro (.fcpxml), and Premiere Pro (xmeml).
